Abstract

The invention is suitable for the technical field of network security, and provides a password cracking method and device, and the method comprises the steps: carrying out the preprocessing of passwords in a training set according to a preset limiting condition, and obtaining a password set in a unified format; performing structure division on the password set to obtain basic structures of all passwords in the password set and a first character string set corresponding to each section in the basic structures; carrying out character string recombination on the first character string set corresponding to each segment to obtain a second character string set; and iteratively generating a candidate password according to the second character string set and the basic structure of the password. The problems of low password iteration generation rate and low accuracy can be solved, the password cracking success rate is improved, and the timeliness of password attack is ensured.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a password cracking method and device. Background technique [0002] With the rapid development of computer network and communication technology, network security has become an important issue in the current information age. Identity authentication is an important line of defense for network security. Passwords have long been the mainstream method of identity authentication due to their simplicity and ease of deployment, and are widely used in e-commerce, online banking, and social media. Password attack is an important means of password security research and one of the important directions of cryptography. Password attack can not only be used in public security forensics and other fields, but also can better test the security of password algorithms and promote the development of password algorithms. [0003] At present, password attack algorithms are mainly...
